Review: Tapworthy – designing great iPhone Apps by Josh Clark

Developing for iPhone is a hot topic. Many developers are not only having to learn Apple’s Objective C and the Cocoa application framework, but are also new to mobile development. It is a big shift. Josh Clark is a iPhone designer, and his book Tapworthy is about how to design apps that people will enjoy using. It is not a programming book; there is not a single snippet of Objective C in it.

His book illustrates the power shift that has taken place in computing. In the early days, it was the developer’s task to make an application that worked, and the user’s task to understand how to use it, through manuals, training courses, or whatever it took.

There are still traces of this approach in the software industry, but when it comes to iPhone apps it has reversed completely. The app creator has to build an app that the user will find intuitive, useful and fun; otherwise – no sale.

An early heading reads “Bored, Fickle and Disloyal”. That’s the target user for your app.

Clark’s point is valid, and he does hammer it home page after page. You will get the message; but it can get tiresome. His style is frank and conversational: some readers will love it, others will find it grating after a chapter or two.

Even if you are one of the latter group, it is worth persevering, because there is a ton of good content here. There are also numerous short interviews with developers of actual apps, many of them well-known, discussing the issues they faced. The persistent issue: we’ve got a complex app, a small screen, and intolerant users, how on earth do we make this seem simple and intuitive?

Constraints like these can actually improve applications. We saw this on the web, as the enforced statelessness and page model of web applications forced developers to simplify the user interface. It is the same with mobile. Joe Hewitt, author of the first generations of Facebook for iPhone:

There is so much stuff that is actually better on the small screen because it requires designers to focus on what’s really important.

So what’s in the book? After a couple of scene-setting chapters, Clark drills down into how to design for a tiny touchscreen. Be a scroll sceptic, he says. Chapter 4 then looks at app structure and navigation. Chapter 5 takes you blow by blow through the iPhone controls and visual elements. Then we get a chapter on making your app distinctive, a chapter on the all-important start-up sequence and how to make seem instantaneous, and a chapter on touch gestures.

The last three chapters cover portrait to landscape flipping, alerts, and finally inter-app communication and integration.

Throughout the book is illustrated in full colour, and the book itself is a pleasure to read with high quality paper and typography. 300 pages that will probably improve your app design and increase its sales; a bargain.

Dropbox: file sync that works, something for Ray Ozzie to think about

2 Comments

It all started when I wanted to get a document onto an iPhone. Apple makes this absurdly difficult, so I installed Dropbox, which does cloud synch of up to 2 GB free, more with subscription, across multiple platforms and devices: Windows, Mac, Linux, iPhone, Android, iPad and soon Blackberry.

I mentioned this on Twitter:

installed dropbox – live mesh but cross-platform and without the hassles?

and got several responses:

Dropbox is brilliant, I sync allsorts with it and use it as main storage on my netbook!

and

love that service, I couldn’t even get live sync to sign in!

and

I just updated my dropbox to the 50GB plan. Now have all my stuff synched across 5 macs/pcs + available on my iPhone.  Amazing

Now, Microsoft’s Live Mesh appeared in April 2008 and was meant to synch files across Windows, Mac and mobile, though the mobile client never really appeared. It has now been replaced by Windows Live Sync. There’s still no mobile support, not even for Windows mobile.

Dropbox launched publicly in September 2008 and now has a team of 28 people according to the About page – including the very capable Adam Gross formerly of Salesforce.com.

It seems to be an example of Microsoft having a good idea but being unable to deliver. The reason I mentioned “without the hassle” in my tweet is that Live Mesh always required a reboot and occasionally caused problems afterwards in my experience. Dropbox did not.

Ray Ozzie is Microsoft’s Chief Software Architect and seemed to be a key driver behind Live Mesh when it was announced. At one time it seemed that the technology might play a fundamental role in Microsoft’s efforts to unite cloud and device.

You can sign up for Dropbox free here.

Lies, damn lies, and Apple’s antenna-gate

Apple’s iPhone 4 is still relatively new; and I when I pulled it out of my pocket at a social occasion last weekend someone said, “isn’t that the new iPhone?” and another, “isn’t that the one with the aerial fault?”

Another person then showed his iPhone 4, with shattered screen. His had been dropped, an expensive slip of the wrist.

So there we have it, the two worst features of Apple’s new phone – fragility, and a dodgy antenna – exposed to all.

I have first hand-evidence then that the antenna issue is well-known. But how much will it affect sales? I received an email today from Opinium Research. According to their survey of 2000 UK adults, 26% are less likely to get an iPhone 4 because of this widely reported fault.

Pretty bad for Apple then – a quarter of their market gone. Well, no. This is an example of “ask a silly question”. If you ask someone, “does the antenna issue make you more or less likely to buy an iPhone 4,” what do you expect them to say? In fact, 13% of them said it was a non-issue, while 57% said it was irrelevant because they are not in the market for an iPhone 4 anyway.

The right question would be: “Have you changed your mind about getting an iPhone 4 because of the reported fault with the antenna?” I expect many fewer would tick the yes box.

Useless survey then. In my view the phone is fine, the antenna issue is minor, and Apple’s free case offer will sort it for most people.

Going back to my social occasion, by the end of the party Apple had at least one more would-be customer, despite the antenna and despite the fragility; and given that the phone is still out of stock everywhere I don’t think the company need worry too much – though its reaction to this wave of bad publicity has been interesting to watch.

Incidentally, I also had a briefing on Windows Phone 7 today – more on that later.

Enterprise app development on Apple iPhone and iPad

2 Comments

Apple’s iPhone is still perceived as primarily marketed to individuals rather than corporates. However, I was interested to see how much Apple is doing to attract corporate developers. First, Apple now supports some basic enterprise-friendly features, such as Microsoft Exchange (with a few caveats), VPN, remote wipe, and the ability to lock down iTunes to some extent. Without these capabilities, the devices would not be acceptable in many environments, making it pointless to consider them for custom applications.

Unfortunately iTunes is still needed for activation, deploying software updates, and installing applications. It is silly that Apple requires business users to install a music library to use its phone, I guess reflecting the device’s history as a music player. It is also a somewhat intrusive application especially on Windows.

If you then want to develop internal applications, you sign up for the iPhone Developer Enterprise Program. At $299 per year this is more expensive than the more general equivalent, but no big deal. Then you have to get a digital certificate from Apple. Next, create one or more “provisioning profiles” that install onto the device and authorize it to run your applications. Applications you create must be signed with your digital certificate. Finally, you can add the signed applications to an iTunes library, and users can then drag them to their iPhone or iPad. It will only run on devices that have the matching provisioning profile installed. Organisations can also revoke applications by revoking the identity used to sign the provisioning profile.

As Adobe pointed out to me, since these apps do not go through Apple’s approval process, there is nothing to stop corporate developers using the Flash Packager for iPhone that is available in Creative Suite 5.

There is more detail on Apple’s iPhone in Business page.

HP will not do Android or Windows Phone 7 smartphones – but what chance for webOS?

1 Comment

HP’s Todd Bradley, Executive Vice President of Personal Systems and formerly CEO of Palm, was interviewed by Jon Fortt at CNBC. Fortt asks some great questions which mostly get woolly answers, but did get this statement from Bradley:

We will not do a Linux, Android phone. We won’t do a Microsoft Phone … we’ll deliver webOS phones.

I will be interested to see if HP sticks to this commitment. HP is Microsoft’s biggest customer and huge in business systems, but that does not necessarily mean it can make a success of a mobile platform on its own.

Mobile platforms stand (or fall) on several pillars: hardware, software, mobile operator partners, and apps. Apple is powering ahead with all of these. Google Android is as well, and has become the obvious choice for vendors (other than HP) who want to ride the wave of a successful platform. Windows Phone 7 faces obvious challenges, but at least in theory Microsoft can make it work though integration with Windows and by offering developers a familiar set of tools, as I’ve noted here.

RIM Blackberry is well entrenched in the Enterprise and succeeds by focusing on messaging and doing it well. Nokia and Intel will jostle for position with MeeGo.

It is obvious that not all these platforms can succeed. If we accept that Apple and Android will occupy the top two rungs of the ladder when it comes to attracting app developers, that means HP webOS cannot do better than third; and I’d speculate that it will be some way lower down than that.

You have to feel for HP, which has supported Microsoft’s failing mobile platform for many years – with the occasional lapse, remember when it became an OEM vendor for Apple’s iPods? – and now has decided it cannot rely on the company in this area. That is understandable. However, HP is heavily invested in Windows. It may be choosing just the wrong moment to abandon ship; or it may find that doing its own thing with webOS is no better. Google Android would have been a safer though less interesting choice.

BBC News app arrives on iPhone

1 Comment

Today the BBC received approval from the BBC Trust to create apps for mobile devices such as Apple iPhone/iPad and Google Android. Wasting no time, the corporation published a BBC News App on the App Store today.   

But what is the point? Is this really better than simply going to the web site:

IMG_0001

It is worse in some ways, because there is a disconnect between content locked in an app, and content on the world web web where it can be linked and searched. There is also an argument over whether the publicly funded BBC creating apps for luxury mobile devices, instead of investing in more public content, though I’d imagine that the cost of creating the app is small relative to the cost of producing the content. The BBC no doubt feels under pressure to keep up with competitors such as Sky News, which already has an app available.

The BBC app becomes more interesting if you click the Live button, though you need a good connection, preferably wi-fi:

The app becomes a news-dedicated iPlayer for iPhone; a full iPlayer is also promised. A nice feature; though even this can be done on the web as long as you use Apple’s QuickTime format rather than not-invented-here Adobe Flash.

Why is there so much junk in Apple’s App Store?

2 Comments

After 4 weeks with Apple’s iPhone 4 I’m mainly impressed with everything other than the call quality (I am in a poor signal area for O2). I’ve been exploring the App Store though, and while there are many great apps there, there is also a huge amount of junk. Here’s a review for an app I was looking at:

This app is such a con. The adverts are deliberately put in the most awkward places so they get pressed accidentally; there is no “would you like to make a call” dialog box, nothing, it goes straight to an 090 number and even if you cancel the call instantly you are still charged … Apple should be ashamed for letting this little con artist on to the app store!

Other users report frequent crashes, lost data and so on.

With over 200,000 apps available, it’s not surprising that some are duds. However, given Apple’s insistence on checking every one, I’d expected the overall standard to be higher. Apple cannot easily judge how useful an app is, particularly in a niche area, but things like instability or unfair advertising practices should be caught.

Another odd thing: if you browse the store on the device, you cannot sort by rating, as far as I can tell, making it hard to find the better apps quickly. I guess this could be designed to mitigate the “winner takes all” factor: if one or two apps in a common search category achieve high ratings, it is difficult for newcomers to get noticed sufficiently to drive up their own ratings. Still, give the amount of dross in there, it would help to have this as an option, even if it were not allowed to be the default sort.

The existence of so many poor apps also puts into context the Thoughts on Flash posted by Steve Jobs. I kind-of understand why Apple wants to exclude the Flash runtime from its device platform; but that does not explain the ban on Adobe’s Packager for iPhone, which compiles a Flash application to an iPhone binary. That might make sense if Jobs could point to the consistent high technical standard of iPhone Apps; but that is simply not the case.

Dysfunctional Microsoft?

2 Comments

Microsoft watchers have been scrutinising the fascinating Mini-Microsoft post on the Kin smartphone debacle and what it says about the company. If it is even slightly accurate, it is pretty bad; and it must be somewhat accurate since we know that the hopeless Kin launch happened and that the product was killed shortly afterwards. Of course it would have been better to kill the project before rather than after the launch; the negative PR impact has affected the strategically important Windows Phone 7 launch.

Handsome profits from Windows and Office have enabled Microsoft to survive and even prosper despite mistakes like Kin, or the Xbox 360 “red ring of death”, or the Vista reset and related problems – mistakes on a scale that would sink many companies.

I see frequent complaints about excessively bureaucratic management with too many layers, and a tendency towards perplexing, ineffective but expensive advertising campaigns.

There are also questions about CEO Steve Ballmer’s suitability for the task. He nearly indulged in a disastrously over-priced takeover of Yahoo, saved only by the obstinacy of the target company’s leadership. He habitually dismisses the competition, such as Apple’s iPhone, and is proved wrong by the market. He failed to see the importance of cloud computing, and even now that the company is at least partially converted he does not set the right tone on the subject. I watched his keynote at the Worldwide Partner Conference (WPC) where he sounded as if he were trying unsuccessfully to imitate Salesforce CEO Marc Benioff from ten years’ ago. Microsoft needs to present a nuanced message about its cloud initiative, not someone shouting “oh cloud oh cloud oh cloud”.

Microsoft is also copying its competition as never before. Bing has a few innovations, but is essentially a recognition that Google got it right and an attempt to muscle in with a copy of its business model – search, advertising and data mining. Windows Phone 7 occupies a similar position with respect to Apple’s iPhone and App Store. Windows 8 also seems to borrow ideas from Apple.

Nevertheless, Microsoft is not yet a dying company, and it would be a mistake to base too much analysis of the company on something like comments to Mini-Microsoft’s blog – good though it is – since it is a magnet for disaffected employees.

While Ballmer’s effort at the WPC was poor, he was followed by Bob Muglia, president of server and tools, who was excellent. Windows Azure has come on remarkably since its half-hearted preview at PDC 2008; and Muglia comes over as someone who knows what he is trying to achieve and how he intends to get there. The Azure “Appliance” idea, shipping a pre-baked cloud infrastructure to Enterprise customers, is a clever way to exploit the demand for a cloud application model but on hardware owned by the customer.

The eBay announcement at WPC was also quite a coup. eBay will “incorporate the Windows Azure platform appliance into two of its datacenters” later this year; and while it is not clear exactly how much of eBay will run on Azure, these appliance kits represent significant hardware.

We’ve seen other strong releases from Microsoft – server 2008 R2, Exchange 2010, SQL Server 2008 R2, SharePoint 2010 which whatever you think of SharePoint is a solid advance on its predecessor, and of course Windows 7 which has done a lot to rescue Microsoft’s performance and reputation after the Vista disappointment.

I also continue to be impressed by Visual Studio 2010, which is a huge release and works pretty well in my experience.

What about Windows Phone 7? With the market focused on iPhone vs Android, clearly it is in a tough market. If there is something slightly wrong with it on launch, instability or some serious hardware or software flaw, it might never recover. Nevertheless, I do not write it off. I think the design effort is intelligent and focused, and that the Silverlight/XNA/.NET development platform along with Visual Studio is an attractive one, especially for Microsoft Platform developers. VP Scott Guthrie describes the latest SDK here. People still switch phones frequently – something I dislike from an environmental point of view, but which works in favour of new entrants to the market. If Windows Phone 7 is a decent device, it can succeed; I’d rate its long-term chances ahead of HP WebOS, for example, and will be keen to try it when it becomes available.

Is there a lot wrong with Microsoft? Yes. Does it need a fresh approach at the very top? Probably. Nevertheless, parts of the company still seem to deliver; and even the Windows Phone 7 team could be among them.

iTunes hacks: whose fault are they?

1 Comment

A big story today concerns irregular activity on Apple’s iTunes store, the one and only means of purchasing applications for iPhone and iPad and central to the company’s strategy. The reports allege that developers are hacking iTunes accounts to purchase and give favourable review to their apps – which can only be a short term strategy since you would imagine that such activity would soon be detected and the perpetrators traced through the payment system.

As it happens I’d been meaning to post about iTunes security in any case. I blogged about an incident just over a month ago, since when there have been a steady stream of comments from other users who say that their iTunes accounts were hacked and fraudulent purchases made.

A recent comment refers to this thread, started over a year ago and now with over 200 comments from similarly afflicted users.

Despite the number of reported incidents, there is no reason to suppose that Apple’s servers have been broken into. Several other mechanisms are more likely, including malware-infected computers on which users may have stored passwords, or have keystrokes logged; or successful attempts to guess passwords or the answer to so-called “security questions” which also give access to account details.

Such questions should be called insecurity questions, since they are really designed to reduce the burden on helpdesks from users who have lost passwords or access to obsolete email accounts. Since they allow access to accounts without knowing the password, they reduce security, and even more so when the questions are for semi-public information like mother’s maiden name, which is commonly used.

Given the number of iTunes accounts, it is not surprising that there are numerous successful hacks, whether or not there is some issue (other than the insecurity questions) with iTunes or Apple’s servers.

That said, there is a consistent theme running through all these threads, which is that Apple’s customer service towards victims of hacking seems poor. Contact is email-only, users are simply referred to their banks, Apple promises further contact within 24 hours that is often not forthcoming, and there are reports of users losing access to credit or previous purchases. It was an instance of the latter which prompted my earlier post.

Apple therefore should fix its customer service, even if its servers are watertight. I’d like to see it lose the insecurity questions too.

What next for Embarcadero Delphi? Roadmap with Mac, Linux support published.

11 Comments

Embarcadero has published an updated roadmap for its Delphi development tools: Delphi, C++Builder and the RAD Studio shared IDE. These tools combine the Object Pascal (Delphi) or C++ language with a visual component library and native code compiler for Windows.

Chief Technical Architect Michael Rozlog outlines four products which are being worked on, including “Fulcrum”, “Wheelhouse”, “Commodore” and “Chromium”. He says work is being undertaken on all of these, so the exact release schedule is not specified. Embarcadero has an annual release cycle for these products so you might reasonably project that Fulcrum is set for release later this year, Wheelhouse for 2011, and Commodore for 2012. Delphi 2010 came out in August 2009.

Delphi “Fulcrum” introduces a cross-compiler for Mac OS X, with the emphasis on client applications. The IDE will run only on WIndows. Rozlog also talks about integration with Microsoft Azure so that Embarcadero can tick the Cloud Computing box.

Delphi “Wheelhouse” adds Linux support, on a similar basis where the IDE runs only on Windows. It also adds a focus on server applications for both Linux and Mac OS X, including support for Apache modules.

Delphi “Commodore” is the 64-bit release, with 64-bit and easier multi-core development on all three platforms. Rozlog also tosses in “Social Networking integration” and “Better documentation”.

2012 is a long time to wait for 64-bit, particularly as the Windows server world is now primarily 64-bit. Embarcadero is promising a 64-bit compiler preview for the first half of 2011, though this will be command-line only.

Delphi “Chromium” is a revamp of the Visual Component Library with a new look and feel and “natural input integration” – location, voice, video motion.

In addition, Rozlog talks about updates for Delphi Prism, which is loosely the Delphi language plus a .NET compiler, and integrates into Visual Studio. Prism 2011 will work with Visual Studio 2010, and includes support for Mono. This extends to working “with MonoTouch to create Apple iPhone ready applications.” Rozlog doesn’t state whether this has been cleared with Apple’s Steve Jobs, who is opposed to use of languages other than Objective C for iPhone or iPad development.

Is Embarcadero doing enough to keep Delphi current? I’m not sure. Delphi is a fantastic RAD and native code compiler for Windows; in the past it suffered when Borland tried to extend it beyond that, to Linux and .NET, distracting development effort from its core role. The risk here is that the Mac and Linux effort may be more of the same. Of course this will be nice to have, though running the IDE on Windows and compiling for Mac is a limitation that means it will not appeal to Mac developers, only to Delphi Windows developers hoping to extend their market. But there are other ways to do cross-platform now –  Silverlight, Flash, web applications – and I wonder if the time for this has passed.

A compiler for iPhone and iPad would now be bigger news, especially since Silverlight and Flash are not available on these platforms, but for this Embarcadero would need to overcome Apple’s cross-compiler restrictions as well as solve the technical problems.

Windows 7 has breathed some new life into Windows client development. I hope Embarcadero is not neglecting areas like great RAD support for features like Jump Lists and thumbnail previews, for the sake of the uncertain cross-compiler market.

There is a discussion of the new Roadmap in the Delphi forums here, and Marco Cantu also comments.
